IMPROVEMENT IN GARRIAGE-KNOB. y

TOlALL WHOM I T MAY CONGERN;V

I 'Be it known thatl I, Ji BRCLAY,`of Attleborough, in the county of Bristol, and State of Massachusetts, have invented a new and improved Carriage-Knob; and I do hereby declare that the following is a full, dlear, and exact description thereof, which will enable others skilled in the art to make and us the same, reference being 'had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a side view, partly in section, ofniy improved carriage-knob.

Figure 2 is an end View of the same.

Figure' 3 is a'perspective view of the same.

vSimilar letters ot' reference indicate corresponding parts.

This invention relates to a new carriage-knob, which is so arranged that the spring jaws, by which the curtain is held, are made detachable from the pins by which they are secured to the carriage, so that when either part is destroyed orl broken itrcan be replaced without losing the other part. The invention consists in securing-two or-more sprngjaws'to'a rin'g,which,is' fitted over the shank ofthe pin so as to rest between the vhead of the same andthe wood-work to which .it is secured. The jaws fit into slots arranged in the head of the pijn and project from the side of the pin to hold the curtain, but can be pressed into the slots to release the same.

A represe'nts the pin of a carriage-knob, of which a is the head and b the shank. The latter may be provided with a screw-thread, as shown, or otherwise so arranged that it can be easily secured in the wood-work of the carriage. i The head is provided with two or more straight slots c'ex-teding from the shoulder formed by the head upon the shank. toward the outer end of the head. i B B are the spring jaws. Two or more of thc same are tted to a ring, d, as is clearly shown in fig. 3. Byfitting the shank of the pin A through the ring d, so that the jaws wilkbe'in line with the slots c, and by then securing the pin A in the wood-work, the parts will be connected for operationv The jaws are wider at their outer ends, forming shoulders e e', as shown in figs. 1 and 3. Whenth'e eyelet of the curtain is pressed upon the end of the knob it forces the jaws into the slots c, the outer ed of thejawsbeing rounded for that purpose, and as it slips over the shoulders e or e it is firmly held on the knob. If the shoulders have sharp edges, as `at e in figs. l and 3, the curtain can only he' released by compressing the jaw-s B, so that they fit into the slots'C, and by their drawing the eyel'et off. If the edges of the shoulders are chamfered, Vas at e in iig. 1, Vthe curtain can be drawn o' by pullingv it over the head of the pin without compressing the jaws by hand, although wind orv the motion of the carriage will not have power enough to pull oil` the curtain. This device may also be used for other 'purposes besides as a carriageknoh. l i

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is A carriage-knob,consisting of'jaws B, secured to a ring, d, which is fitted loosely over the shank of a. pin, A, provided with slots C upon the -sides of 'the head, all made and operating substantially as herein shown and described. v l I I v t JOHN BARCLAY.
